Technology That Drives Precision Design

We leverage a full suite of industry-leading software to ensure every detail of your mold is meticulously planned, simulated, and optimized for performance before the first piece of steel is cut.

 

Key areas where we provide value‑added suggestions

We partner with you from the very first sketch — every recommendation is aimed at lowering your total cost, improving quality, and speeding up production.

Part Design Optimization

Tips: fewer operations = lower cost

We review your part geometry to recommend design modifications that simplify the mold structure, reduce material usage, and minimize secondary operations—without compromising functionality.

Wall Thickness Uniformity

Tips: consistent walls = higher yield

Uneven wall thickness can lead to defects like porosity or shrinkage. We guide you in achieving consistent wall thickness for better quality and lower rejection rates.

Draft Angle Recommendations

Tips: optimal draft = longer tool life

Proper draft angles are essential for easy ejection and longer tool life. We calculate the optimal angles based on your part’s geometry and alloy selection.

Gate & Runner System Layout

Tips: smooth flow = less scrap

Our simulations help position gates and runners strategically to ensure smooth metal flow, reduce turbulence, and minimize scrap—saving you money on every shot.

Material Selection Advice

Tips: right alloy = best value

Choosing the right aluminum alloy can impact both performance and cost. We help you select the most cost-effective alloy that meets your mechanical and thermal requirements.

Tolerance Feasibility

Tips: smart tolerances = lower mold cost

We review your part geometry to recommend design modifications that simplify the mold structure, reduce material usage, and minimize secondary operations—without compromising functionality.

Cooling System Integration

Tips: shorter cycles = higher output

Efficient cooling reduces cycle time and improves part consistency. We design conformal cooling channels that speed up production and extend mold life.

Cost Estimation & Value Engineering

Tips:volume optimization = savings

We provide transparent cost breakdowns and suggest alternative approaches—like multi-cavity molds or family molds—to lower per-part costs in high-volume runs.

Our Proven Mold Development Process

We follow a rigorous, stage-gate process to ensure transparency, accountability, and predictable results for every project.

 

Step 1

Requirement Analysis

We begin with a deep dive into your project, capturing all technical specifications, critical requirements, and performance goals to ensure a comprehensive understanding and project feasibility.

 

Step 2

Design, Simulation & Optimization

Our engineers create the 3D tooling design and provide a detailed DFM report. We then use advanced mold flow analysis to simulate and optimize gating, cooling, and venting, proactively solving potential issues to ensure a robust and efficient mold design.

 

Step 3

Final Design Review & Approval

We present the final, fully optimized tooling design for your review and formal client approval. This collaborative milestone ensures complete alignment on all technical details and the project timeline before manufacturing begins.

 

Step 4

Precision Manufacturing

Our skilled technicians utilize high-speed CNC machining, precision EDM, and grinding machines to manufacture each mold component to exact specifications, adhering to critical tolerances under strict in-process quality control.

Step 5

Mold Assembly & Trials

The meticulously crafted components are assembled by our expert mold makers. We then conduct the initial T1 trial, optimizing process parameters to produce the first samples for validation.

Step 6

Sample Inspection & Delivery

We perform a comprehensive First Article Inspection (FAI) on the trial samples and provide a full dimensional report. Upon your approval, the mold is prepared for shipment or ready to commence mass production, seamlessly integrating into your supply chain.

FAQs on High Precision CNC Machine

What is the typical lead time for a new mold?

Typically, a new die casting mold takes between 4 to 8 weeks to complete, from final design approval to the T1 trial. The exact timeline depends on the mold’s complexity, size, and the number of cavities required. We provide a detailed project schedule for every order.

What factors influence the cost of a mold?

The primary cost drivers for a mold are the part’s complexity and size, the type of mold steel used (e.g., H13, 8407), the required mold lifespan (number of shots), the number of cavities, and the complexity of any side-actions or slides.

What information do I need to provide for an accurate quote?

For the most accurate quote, please provide your 3D models (STEP, IGS, or X_T format), 2D drawings with tolerances specified, the material of the final cast part, and the estimated annual production volume or required mold life.

What is the expected lifespan of your molds?

The lifespan of our molds varies based on the steel quality and part complexity, typically ranging from 300,000 to over 1 million shots. We use premium steel from trusted suppliers like ASSAB and LKM and follow rigorous heat treatment protocols to maximize tool durability and performance.

How do you protect our intellectual property (IP)?

We take intellectual property protection very seriously. We are committed to signing a Non-Disclosure Agreement (NDA) before any project begins. All design files and project data are stored on a secure, access-restricted server, and we guarantee that your design will only be used exclusively for your project.

Do you also offer die casting production services after the mold is built?

Yes, absolutely. While we can ship the mold to your facility, we are also a full-service die casting manufacturer. Most of our clients benefit from our seamless “one-stop” service, where the newly built mold is transferred directly to our in-house die casting lines for mass production, ensuring optimal performance and accountability.

What is your policy on mold modifications or engineering changes?

We understand that engineering changes are a normal part of the product lifecycle. We maintain all original design data and can provide modification services for molds we have built. We will evaluate the requested changes, provide a detailed technical proposal and quote, and execute the modifications efficiently to minimize any production downtime.
